IMPROVEMENT IN CHURN-POWERS.

Specification forming part of Letters Patent No. 222, [47,

dated December 2, 1879; application filed November 1, 1879.

it appertains to make and usethe same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention is an improvementon Letters Patent granted to me on the 29th day of.July, 1879, and numbered 217,892, for

hand-powers for operating churns and lightmachinery; and it consists in the novel construction and arrangement of the same, whereby an easier movement is given to the different parts ofwhich it is constructed, in operating a churlrdasher or light machinery to which said power may be applied, all of which will be hereinafter more fully explained.

The annexed drawings, to which reference is made, fully illustrates my invention, in which- Figure 1 represents a vertical sectional view of my improved hand-power applied to an ordinary churn. Fig. 2 represents an end view of the same, and Fig. 3 represents a detail View.

The capital letters A A designate vertical standards arising from a base, a, to which the lower ends of said standards are permanently fixed, and are joined to one another by crosspieces a a and upper cross-pieces, a a Said standard A is provided with a perforation running crosswise the same, through which is passed a bolt,a onthe inner end of which and between the standards A A is placed a fly-wheel, B, revolving loosely thereon. Said fly-wheel B is provided with a crank, O, the end 0 of which enters a perforation or a slot formed in one of the bars b in the fly-wheel B, and is secured thereto. The horizontal portion I) of said crank has pivoted thereto and arising therefrom a rod, D, the upper end, d, of which connects and is pivoted to a handlever, E, at or nearits center. Theinner end,

(1, of said lever is also pivoted to the crosspiece (6*, which connects the standards A A to one another. The outer end, 0, of the lever aforesaid is formed into a handle, by which the churn-power is operated.

F represents a pitman or which is connected to b of the crank (l, and is provided with washers 0 similar to the washers c on the opposite portion, 12, on which works the rod D. The opposite end of the pitman or rod F connects with the forward end of a second lever, G. The inner end, 9, the cross-piece a between the standards aforesaid, as' shown in Figs. 1 and 2 of the drawings.

Having explained the difl'erent parts of which my improved churn-power is constructed, I will now proceed to describe the mode in which it is operated. The handleeof the handlever E is given an up-and-down movement. This is allowed by the inner end of the same being pivoted as above described. At the same time the connecting rod D moves with said hand-lever and causes the fly-wheel B to revolve and carry the crank O therewith. This movement of said crank imparts a vertical movement to the end of the lever G, through the medium of the pitman or rod F. The inner end, 9, of the lever G being pivoted to the cross-piece o connecting the standards A A, as herei-nbefore described, allows of such vertical movement to the outer end of said lever, in order to operate a churn, as shown in Fig. I of the annexed drawings.

It will thus be seen by the foregoing description that a churn-power constructed as herein shown and described is simple in its construction, and easily operated by a slight pressure upon the handle 6 by the operator. At the same time the crank before mentioned prevents and overcomes a dead-center in the revolution of the fly-wheel B, and thus prevents the different parts of the power from receiving a shock in starting the fly-wheel.

rod the end, f, of

I may attach a simple device in the shape of a swinging arm, the upper part being pivoted in a slot made in the outer end of the lever G, and in the lower end of said swinging arm I form an eye, through which passes the upper the horizontal portion of said lever is pivoted to end of a dasher-rod of a churn, said rod being ing arranged to operate as herein shown and held in said eye by a pin or thumb-screw rundescribed, and for the purposes set forth. ning crosswise the same. In testimony that I claim the foregoing I Having thus described my invention, What have hereunto set my hand this 28th day of I claim as new, and desire to secure by Let- October, 1879.
